If Naruto characters read the future in a fanfic, it would be a really interesting concept. Naruto himself would be faced with the knowledge of things to come. He might see the fates of his friends and comrades. This could lead to him trying to train harder or change certain events. Sakura could also be affected. If she saw a future where she was still weak, she might strive to become stronger. And for the villains, like Pain, if he saw a future where his plans failed, he might come up with new and more devious strategies. All in all, it would completely disrupt the normal flow of events in the Naruto world within the fanfic.
The older characters such as Kakashi would be cautious. They would recognize Naruto but also be worried about the implications of someone from the future being in the present. They would want to know if his presence could change the future in a negative way. For example, they might fear that his actions could lead to the earlier awakening of a powerful enemy. As for the villains, they might see future Naruto as a threat and try to eliminate him as soon as possible. Orochimaru, for instance, would be very interested in Naruto's future powers and might try to capture him to study. And the new generation of ninja in the past would look up to future Naruto, seeing him as a symbol of what they could become.
In a 'naruto future orb fanfic', the main characters might be a group of young and inexperienced ninjas who accidentally stumble upon the orb. They could include a headstrong male lead who is eager to prove himself, a smart female character who tries to figure out the orb's secrets, and a mentor - like figure who has some knowledge about the orb from the past. These characters would then embark on a journey filled with challenges and revelations related to the orb.
Naruto is the central character, no doubt. Hinata could be important as well. If Naruto sees a future related to his family or his relationship with Hinata, she will play a significant role. Additionally, the Hokage, like Tsunade or whoever is in charge at that time, would be important as Naruto may need to report the future he saw to the village leadership to take collective action.
Obviously Naruto is one of the main characters since it's about him watching the future. Sasuke would also likely be a key character, given their long - standing relationship. And Kakashi, as Naruto's former teacher, could play an important role too.
Naruto would likely be excited yet a bit scared. He'd be eager to make the future a better place but also worried about the bad things he might see. Sasuke would probably be more reserved, analyzing the future information carefully. Hinata would be shy about it but also determined to protect those she loves if she saw any danger in the future for them.
They might be shocked. For example, Naruto himself, if he reads about future threats to the village in the fanfiction, he would probably start preparing immediately to protect his friends and the Hidden Leaf. It could change their present actions as they try to avoid bad futures or work towards good ones.
There could be their children's friends. Maybe a young ninja from a far - off village who comes to study in the Hidden Leaf. His unique abilities and different cultural background could bring new elements to the story.
Naruto would be excited and ready to face whatever comes. He's always been positive and believing in his ability to change things. So, he'd see it as a challenge to make the future better.
Naruto might encounter future versions of the kages from different villages. These kages could have different leadership styles influenced by the development of the future world. He may also run into new characters who have emerged as heroes or villains in this new era.
